Opportunistic use involves extrinsic motivation, with identified and/or external regulation (Deci and Ryan, 2008), and, hence, differing degrees of self-determination. It fulfills the users’ aim to improve efficiency in their tasks or jobs (‘‘[with IT], I can do some of the things I have to do better and much faster”: professor). IT is seen as instrumental in practicalneeds fulfillment. When opportunistic use is high, IT is used to achieve tasks more efficiently (identified regulation: Deci and Ryan, 2008 – ‘‘Since I started to use IT, I am much more efficient in my work”: CEO). When the assessment of this type of use is low, usage is mostly limited to a few software functionalities, in order to comply with hierarchical instructions in a reward-punishment approach (external regulation: Deci and Ryan, 2008 – ‘‘I use only the functionalities I am told I have to use for my job by my boss”: PR manager). In this case, it may then be considered as resulting from ‘‘subjective norm” – that is, the perceived social pressure to perform (or not perform) a given behavior (Ajzen, 1991; Davis et al., 1989; Fishbein and Azjen, 1975; Mathieson, 1991; Taylor and Todd, 1995a, 1995b).
